IMPROVEMENT IN TUMBLER-WASHERS.

Specification formingv part of Letters Patent No. 154,759, datedSeptember 8, 1874; application filed April 21, 1874.

1o all whom it may concern:

Be it known that we, FERDINAND LAUTEN- BACH and JOHN C; HAMMEN, both ofthe city of Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Tumbler-Washers, of which the followingis a specification:

Our invention relates to a tumbler-washer of that well-known class inwhich the tumbler is placed bottom up upon a stand, through whichprojects a jet-pipe, the, water from which is caused to issue andimpinge against and wash'the inside of the tumbler simply by placing thetumbler upon the stand, its weight opening a valve and allowing thepassage of the water from a supply-pipe to the jet-pipe, the valve beingautomatically closed and the jet stopped when the tumbler is removed.

The subject-matter claimed will hereinafter be set forth. t Y

In the accompanying drawings, Figure 1 represents a vertical centralsection through our improved tumbler-washer with the jetpipe valve open;andFig. 2, a similar section through a portion of one of the jet-pipesand its branchvpipe, showing theA valve closed.

We have shown in the drawings only one set of jets, one tumbler-stand,and one branch pipe5hbut these parts are, of course, to be duplicated.

The base A is formed with an annular depression to constitute a basin,into which the waste-Water ilows, and from which it is conducted by asuitable waste-pipe. A main supply pipe, B, passes centrally through thebasin. A series of branch pipes, G, project laterally from thesupply-pipe B, to which they are rmly united. At the outer end of eachbranch pipe is a jet-pipe, H. The opening from the jet-pipe into thebranch pipe is ordinarily closed by means of a valve, I, held in linewith the opening by means of a coiled spring, J, incased in the lowerpart of the jet-pipe, and encircling the valve-stem J and bearing at oneend against the valve, and at the other against a cap, K, screwed ontothe lower end of the jet-pipe, so that it can be removed when desired. Arest or support, L, for a tumbler-stand, M, is secured upon or over eachbranch pipe. The jet-pipe H' projects centrally through the rest andstand. The stand is connected with its support by means of rods N,secured to the under side of the stand, and passing through holes in thesupport, so that the stand may have a limited vertical movement on itssupport. The lower ends of the rods N rest on a cage, composed of aloose ring or collar, O,inc1osing the jet-pipe, and connected, by armsP, with another collar, Q, resting on top of a nut, R, screwed to thelower threaded end of the valvestem J y.

By this construction, when the tumbler is placed bottom up upon thestand M, its weight bears upon the valve-stem, which is held up by thecoiled spring J, and compresses the spring, drawing down the valve I,and open- 1ng communication between the supply-pipe and the jet-pipethrough the branch pipe without altering in any manner the position ofthe jet-pipe, which always remains in the same lixed position'. Ihe jetfrom the pipe H washes the inside of the tumbler, and the jet from thereservoir, through the head F, washes the outside of the tumbler. Whenthe tumbler is removed from the stand the valve is closed automaticallyby the spring.

By means of the screw-cap K and nut R the tension of the spring may beregulated, andthe spring may readily be removed when desired.

As the Valve moves across the opening from the jet-pipe to the branchpipe there is no pressure of the water to be overcome in the closing ofthe valve, and as the valve-stem spring is entirely inclosed beneath thevalve and water-passage, it is thoroughly protected from injury bymoisture or other causes.

It is obvious that the rest L for the tumbler-stand may be dispensedwith, and the stand be supported by the jet-pipe-for instance, the cagemay fit snugly, and slide upon the pipe and valve-stem.

We claim- In a tumbler-Washer, the combination of the jet-pipe, thebranch pipe, and a valve arranged within said jet-pipe to move acrossthe branch pipe, as and for the purposesV specified.

In testimony whereof we have hereunto subscribed our names.
